Large structures like long pipelines and offshore wind turbines cannot employ passive galvanic cathodic protection for protection against corrosion. Instead an external power source is utilized (active cathodic protection) to deliver the required electrical current. High power (1000W and 1500W) HWS models, backed by a limited lifetime warranty, were picked because of their long field life and durability.
